Project Summary
This project aimed to look at the spatial variability of Symbiodinium clades C and D in the Kane’ohe Bay, O’ahu, Hawai’i population of Montipora capitata. We investigated the distribution of symbionts at scales ranging from location in the bay to location on an individual reef. We also looked at differences among reef types (fringing vs. patch), colony color morph (brown vs. orange) and depth. Heterogeneous mixtures of symbiont clades were considered in the analysis for spatial patterns. By investigating spatial variability of Symbiodinium, we furthered the understanding of stress-response potential in Kane’ohe Bay.

To account for the influence of tides, depth was adjusted according to the difference in sea level from the mean sea level on each collection day at 6-minute intervals. Mean sea level was obtained from NOAA tide tables for Moku o Lo’e.

When looking at D-only colonies, the Ct values are on the higher end of the spectrum (35 or greater) indicating poor amplification and the potential for C amplification being pushed back in the cycle. This is supported by the fact that 5 of the 9 D-only colonies had C present in 1 qPCR replicate.

When considering the effect of bay area on the interaction of color morph and dominant symbiont, the proportion of Brown colonies dominated by D increases as you move from the north to the south of the bay. The proportion increases almost 6x, yet the small number of colonies makes this non-compelling.
